Application filed December 12, 1928. Serial No. 825,525.

This invention relates to an improved cooler and humidifier adapted to be used for cooling and moistening the air in a room, rcceptacle or the like.

The invention herein shown and described is an improvement on a co-pending application filed byme under date of June 30, 1928, and desi ated by Serial Number 289, 174.

An ob ect of the present invention, like my rior invention is to rovide a small compact iumidifier which is c aracterized by eilicient moisture supplying means, wherein a comparatively large moistened surface area is provided.

1 A brief reference to the co-pending case above indentified will show that it embodies a novel moisture supplying unit in the form of a battery of lates having their surfaces covered by absor ent material, the plates be- 2 ing disposed in s aced relation in order to provide air-circu ating passages therebetween, and the unit being arranged so that its lower portion rests within a water pan, with its upper portion projecting above the pan for cooperation with an air-circulating fan or the like.

In the prior structure just analyzed it will be observed that the vertical plates are bolted together in longitudinally spaced relation.' It'is the object of the present structure, however, to provide a. special openened box mounted on top of the pan and forming an enclosure for a plurality of individual plates removably held in place in order that they may be removed for cleaning, repairing or replacement. p

Other features and advantages of the invention will become more readily apparent from the following description and drawing.

Figure l is a vertical sectional view through the improved structure.

lFi re 2 is a horizontal section taken approximately upon the plane of the irregular line 22 of Figure 1.

Figure 3 is a transverse vertical sectional view taken approximately on the plane of the line 33 of Figure 1. i Figure 4 is a fragmentary perspective view of one of the removable plates.

Referring-now to the drawing by reference numerals it will be seen that the reference character 5 designates generally a water pan of appropriate dimensions, having an inturned guard flange 6 at the to This flange provides an anti-splash guar and also provides a base on which the upstanding boxlike casing 7 is mounted. The casing is 7 preferably rigidly fastened to the flange by soldering Welding or otherwise. This casing is provided with a removable cover 8 and is open at its opposite ends. In fact at the top are short depending end walls 9 having an inturned flange 10 provided with longitudinally spaced notches forming guide slots. In this connection it will be observed that the inner end portions of the flange 6 of the pan are provided with longitudinally spaced notches as at 11 forming additional guide slots. These register with the first-named guide slots and are thereby adapted for removable reception of the improved plates 12. In this form of the invention I also propose to provide axbattery of plates which are spaced apart to function as. partitions and to define longitudinal passages for air currents. T In this form of the invention it is also proposed to use an air circulating fan or the like (not shown) for producing a rapid circulation ofair between the plates. The important point to bear in mind, however, is an that the plates are. individually removable for cleaning and repairing.

Each plate.is of the construction seen in Figure 4. As here represented 13 designates a metallic core member or plate whose opposite faces are covered by a layer of blotter paper or moisture-absorbing material 14. The sheets 14 in turn are covered by sheets of fabric 15 also of an absorbent character. In addition a metal retaining rim 16 is pro 90, vided around the margin to hold the elements 1e and 15 in place and to render each unit of the battery rigid.

It is obvious that the plates are of a size to permit them to he slipped down through the various guide slots in order that the plates may rest on the bottom of the pan and be submerged in the water in the pan. Incidentally it Will benoticcd that the metal rim .16 does not extend across the bottom edges of came thoroughly welt-ed, and as the rnoistur evaporates or is absorbed there'trorn by th air circulating between the plows emanate from the discharge end o ing and be forced into the room or other re ceptacle. ()bviously, when the air is rapidly circulated between the plates, a correspondingly rapid evaporation of water ta place with a consequent absorption of he can the plates, whereby the humidified air emerging from between the plates will he appreciably cooled or lowered in temperature.

In this way a very simple and durable moisture-supplying structure is provided which may be readily and economically manufactured, and disassembled or taken apart for cleaning or repair.

It is also evident that by removing the cover 8 from the box-like casing, the plates 12 are rendered accessible to be removed or replaced, thereby permitting the structure to be maintained in eflicientworking order at all times.

A structure of this class is highly desirable for use as a moistener in cigar cases. However it isnot to be restricted to this use since it may well be adapted for cooling as well as humidiiying purposes. It is thought however that by considering the description in connection with the drawing a clear understanding of the invention will be held.

Finally, by way of cantrast, it will be clear that a structure of this class is an improvement upon any co-pending case and upon other known patented and marketed structures for thesame or similar purposes. Then too, the structure in addition to being compact and convenient in construction and arrangement, is unusually economical and entirely suitable for accomplishing the desired results in an eliicient manner. Therefore, a

' more lengthy description is regarded unnecessary. 4

Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice if desired.

What is claimed is:

1. In a cooler and humidifier of the class described, a water pan having an inturned flange at its top forming an anti-splash guard, the opposite end portions ot'said guard being provided with longitudinally spaced notches functioning as guide slots, and a plurality of moisture absorbent units hav ing their lower end portions resting in said pan and their vertical end edge portions removably seated in said guide slots, and an open-ended casing resting on said flange it follows and surrounding the upper projecting portions of said units.

2. In a cooler and humidifier of the class described, a water pan, an open-ended cas mounted on said pan, a removable cover said casing, said casing having short depending end walls at its opposite open ends, t end walls being provided intur ed i1oriao ""lly disposed flanges equipped with unctio 'n c s guide slots, and a longitudinally extending c absorbent units their lower portions resting in said pan and zneir up= end portions engaged in said guide slot-s.

having an inturned top flange, n

hetween the projecting upper portions thereoi, absorbent coverings on said plates for supplying moisture from said pan to the air lowing through said passages, and a cover mounted over the tops of said plates, said inturned top flange of the water pan having spaced notches in opposed portions thereof forming guide slots in which the vertical edges of the lower portions of said plates are removably seated.

a. A structure as specified in claim 1, wherein the casing is provided at opposite ends and near the top with inturned flanges having notches forming guide slots in which the upper portions of said plates are engaged.

5. A coolerand humidifier comprising a water pan having an inturned top flange, a plurality of spaced vertical plates removably resting in and projecting upwardly from said water pan toprovidehorizontal air passages between the projecting upper portions thereor", absorbent coverings on said plates for supplying moisture from said pan to the air flowing through said passages, and a cover mounted over the tops of said plates, and an open ended casing secured on the top flange of said water pan and surrounding the upper projecting portions of said plates, said cover being fitted on and closing the top of said casing.
